Windows 11 is the latest major release ofMicrosoft'sWindows NT operating system, released on October 5, 2021 as the successor toWindows 10 (2015). It is provided for free for any Windows 10 devices that meet the newWindows 11 system requirements. Aserver version,Windows Server 2025, was released in 2024. Windows 11 is the first major version of Windows NT without a companion mobile version following the discontinuation ofWindows Phone withWindows 10 Mobile.
Windows 11 features major changes to theWindows shell influenced by the canceledWindows 10X, including a redesignedStart menu, the replacement of its "live tiles" with a separate "Widgets" panel on thetaskbar, the ability to create tiled sets of windows that can be minimized and restored from the taskbar as a group, and new gaming technologies inherited fromXbox Series X and Series S such as AutoHDR andDirectStorage on compatible hardware.Internet Explorer (IE) has been replaced by theChromium-basedMicrosoft Edge as the default web browser, like its predecessor, Windows 10, andMicrosoft Teams is integrated into the Windows shell. Microsoft also announced plans to allow more flexibility in software that can be distributed via theMicrosoft Store and to supportAndroid apps on Windows 11 (including a partnership withAmazon to make itsapp store available for the purpose).
Citing security considerations, the system requirements for Windows 11 were increased over Windows 10; Microsoft only officially supports the operating system on devices using aneighth-generation Intel Core CPU or newer (with some minor exceptions), asecond-generation AMD Ryzen CPU or newer, or aQualcomm Snapdragon 850 ARM system-on-chip or newer, withUEFI andTrusted Platform Module (TPM) 2.0 supported and enabled. There are some exceptions to these requirements, however(see:§ System requirements for details). While the OS can be installed on devices with unsupported configurations, Microsoft does not guarantee the availability ofupdates. Furthermore, Windows 11 completely removes support for32-bit CPUs, including both 32-bit x86 and 32-bit ARM processors, ensuring compatibility only with 64-bitx86-64 andARM64 processors.
Windows 11 received a mixed reception at launch. Pre-release coverage of the operating system focused on its stricter hardware requirements, with discussions over whether they were legitimately intended to improve the security of Windows, or as a ploy toupsell customers to newer devices, and over thee-waste associated with the changes. Upon release, it was praised for its improved visual design, window management, and stronger focus on security, but was criticized for various modifications to aspects of its user interface that were seen as worse than its predecessor; some were seen as an attempt to dissuade users from switching to competing applications.[18] Additionally, some users have pointed out disadvantages such as the removal of features like the ability to move the taskbar and increased system requirements that may exclude older devices.[19]
Development
At the 2015Ignite conference, Microsoft employee Jerry Nixon stated thatWindows 10 would be the "last version of Windows".[20][21] The operating system was consideredto be a service, with new builds and updates to be released over time.[22]PC World argued that the widely reported comment was howevertaken out of context, noting that the official event transcript marks it only as asegue rather than a core part of the talk. It argues that Nixon was referring to the fact that he could talk freely at the event because 10 was the last version in current development.[23]
In October 2019, Microsoft announced "Windows 10X", a future edition of Windows 10 designed exclusively fordual-touchscreen devices such as the then-upcomingSurface Neo. It featured a modified user interface designed around context-sensitive "postures" for different screen configurations and usage scenarios, and changes such as a centered taskbar and updatedStart menu without Windows 10's "live tiles". Legacy Windows applications would also be required to run in "containers" to ensure performance and power optimization. Microsoft stated that it planned to release Windows 10X devices by the end of 2020.[24][25][26]
In May 2020, during theCOVID-19 pandemic,Panos Panay, Microsoft's chief product officer forMicrosoft Windows andMicrosoft Office, stated that "as we continue to put customers' needs at the forefront, we need to focus on meeting customers where they are now", and announced that Windows 10X would only launch on single-screen devices at first, and that Microsoft would "continue to look for the right moment, in conjunction with our OEM partners, to bring dual-screen devices to market".[27][28]
In October 2020, reports emerged that Microsoft was working on a user interface refresh for Windows 10 codenamed "Sun Valley", scheduled to be included in a late-2021 feature update codenamed "Cobalt". Internal documentation stated that the aim for "Sun Valley" was to "reinvigorat[e]" the Windows user interface and make it more "fluid", with a more consistent application ofWinUI, while reports suggested Microsoft planned to adapt UI elements seen in Windows 10X.[29] In January 2021, it was reported that a job listing referring to a "sweeping visual rejuvenation of Windows" had been posted by Microsoft.[30]
By December 2020, Microsoft had begun to implement and announce some of these visual changes and other new features on Windows 10 Insider Preview builds, such as new system icons (which also included the replacement of shell resources dating back as far asWindows 95),[31] improvements toTask View to allow changing the wallpaper on eachvirtual desktop,x86-64 emulation on ARM, and adding the Auto HDR feature fromXbox Series X.[32][33][34]
On May 18, 2021, Head of Windows Servicing and Delivery John Cable stated that Windows 10X had been canceled and that Microsoft would be "accelerating the integration of key foundational 10X technology into other parts of Windows and products at the company".[35]
Announcement
At theMicrosoft Build 2021 developer conference, CEO and chairmanSatya Nadella teased about the existence of the next generation of Windows during hiskeynote speech. According to Nadella, he had been self-hosting it for several months. He also teased that an official announcement would come very soon.[36] Just a week after Nadella's keynote, Microsoft started sending invitations for a dedicated Windows media event at 11:00 a.m.ET on June24, 2021.[37][38] Microsoft also posted an 11-minute video of Windows start-up sounds toYouTube on June10, 2021, with many people speculating both the time of the Microsoft event and the duration of the Windows start-up sound video to be a reference to the name of the operating system as Windows 11.[39][40]
On June 24, 2021, Windows 11 was officially announced at avirtual event hosted byChief Product OfficerPanos Panay.[38][41][42] According to Nadella, Windows 11 is "a re-imagining of the operating system".[43] Further details for developers such as updates to theMicrosoft Store, the newWindows App SDK (code-named "Project Reunion"), new Fluent Design guidelines, and more were discussed during another developer-focused event on the same day.[44][45][46]
Release and marketing
The Windows 11 name was accidentally released in an official Microsoft support document in June 2021.[47][48] Leaked images of a purported beta build of Windows 11's desktop surfaced online later on June 15, 2021,[49][50] which were followed by a leak of the aforementioned build on the same day.[51] The screenshots and leaked build show an interface resembling that of the canceled Windows 10X, alongside a redesignedout-of-box experience (OOBE) and Windows 11 branding.[52] Microsoft would later confirm the authenticity of the leaked beta, with Panay stating that it was an "early weird build".[53][54]
At the June 24 media event, Microsoft also announced that Windows 11 would be released in "Holiday 2021".[55][56] Its release will be accompanied by a free upgrade for compatible Windows 10 devices throughWindows Update.[57] On June 28, Microsoft announced the release of the first preview build and SDK of Windows 11 toWindows Insiders.[58]
On August 31, 2021, Microsoft announced that Windows 11 was to be released on October 5, 2021.[59] The release would be phased, with newer eligible devices to be offered the upgrade first.[8] Since its predecessor Windows 10 was released on July 29, 2015, more than six years earlier, this is the longest time span between successive releases of Microsoft Windows operating systems, beating the time betweenWindows XP (released on October 25, 2001) andWindows Vista (released on January 30, 2007).[60]
The first television commercial for Windows 11 premiered during the2021NFL Kickoff Game on September 9, 2021; it was intended to showcase a "feeling of immersion and fluidity", with imagery of operating system features andXbox Game Studios'Halo Infinite.[61] Other promotional campaigns on release day included theBurj Khalifa inDubai being illuminated with imagery of the Windows 11 logo and default "Bloom" wallpaper,[62] and Mikey Likes It ice cream parlors in New York City distributing free cups of "Bloomberry" ice cream.[63][64]
Though a support document listed October 4, 2021, as the initial release date,[65] Microsoft officially released Windows 11 on October 5, 2021,[8][66] as an opt-in, in-place upgrade through either the Windows 11 Installation Assistant application (which can perform the upgrade, or generate anISO image or USB install media), or via Windows Update in a phased rollout; Microsoft anticipated that Windows 11 would be available via Windows Update to all eligible devices by mid-2022.[67][68][69] New installations of Windows 10 on eligible hardware may present an option to upgrade during the OOBE.[70] Retail copies of Windows 11 (consisting of alicense key andUSB flash drive) were released on May 9, 2022,[71][72] and digital licenses became available viaMicrosoft Store on July 28, 2022.[73] On September 20, 2023, around two years after the release date of Windows 11, Microsoft announced that users would no longer be able to use Windows 7 or Windows 8/8.1 keys to activate Windows 10/11.[74] However, as of 2024, there are some reports that they still work, under certain conditions.[75][76]
Windows 11, the first major Windows release since 2015, builds upon its predecessor by revamping the user interface to follow Microsoft's newFluent Design guidelines. The redesign, which focuses onease of use and flexibility,[57] comes alongside new productivity and social features and updates to security and accessibility, addressing some of the deficiencies ofWindows 10.[77]
The collaboration platformMicrosoft Teams is integrated into the Windows 11 user interface, and is accessible via the taskbar.[81]Skype will no longer be bundled with the OS by default.[82][83][84] In early 2023, thePhone Link app gained limited support foriMessage.[85][86][87]
Microsoft claims performance improvements such as smaller update sizes, faster web browsing in "any browser", faster wake time from sleep mode, and fasterWindows Hello authentication.[82][88]
Windows 11 ships with theChromium-basedMicrosoft Edge web browser (for compatibility[89][90] withGoogle Chrome web browser[91]), and does not include or supportInternet Explorer.[92] Its rendering engineMSHTML (Trident) is still included with the operating system for backwards compatibility reasons, and Edge can be configured withGroup Policy to render whitelisted websites in "IE Mode" (which still uses IE's rendering engineMSHTML, instead ofBlink layout engine).[93] Windows 11 is the first version of Windows since the original retail release ofWindows 95 to not ship with Internet Explorer.[94] To comply with theDigital Markets Act, Microsoft is allowing users in theEuropean Economic Area to remove the Microsoft Edge browser,Microsoft Bing search engine, and advertisements to comply with users' interests.[95][96][97]
A redesigned user interface is present frequently throughout the operating system, building upon theFluent Design System; translucency, shadows, a new color palette, and a rounded geometry are prevalent throughout the UI. A prevalent aspect of the design is an appearance known as "Mica", described as an "opaque, dynamic material that incorporates theme and desktop wallpaper to paint the background of long-lived windows such as apps and settings".[101][102] Much of the interface and start menu takes heavy inspiration from the now-canceled Windows 10X.[103] TheSegoe UI font used sinceWindows Vista has been updated to avariable version, improving its ability to scale between different display resolutions.[104]
The flyout for the volume and brightness control in Windows 11 version 22H2 onwards
Thetaskbar's buttons are center-aligned by default, and it is permanently pinned to the bottom edge of the screen; it cannot be moved to the top, left, or right edges of the screen as in previous versions of Windows without manual changes to theregistry.[105] The notifications sidebar is now accessed by clicking the date and time, with other Quick Actions toggles, as well as volume, brightness, and media playback controls, moved to a new settings pop-up displayed by clicking on the system tray. The "Widgets" button on the taskbar displays a panel withMicrosoft Start,[106] anews aggregator with personalized stories and content (expanding upon the "news and interests" panel introduced in later builds of Windows 10).[88][101]Microsoft Teams is similarly integrated with the taskbar, with a pop-up showing a list of recent conversations.[84]
TheStart menu has been significantly redesigned, replacing the "live tiles" used byWindows 8.x and 10 with a grid of "pinned" applications, and a list of recent applications and documents.[82][88]File Explorer was updated to replace itsribbon toolbar with a more traditionaltoolbar, while itscontext menus have been redesigned to move some tasks (such as copy and paste) to a toolbar along the top of the menu, and hide other operations under an overflow menu.[101]
The redesigned Task View in Windows 11, featuring a separate wallpaper support for individual desktops
Task View, a feature introduced in Windows 10, features a refreshed design, and supports giving separate wallpapers to eachvirtual desktop. The window snapping functionality has been enhanced with two additional features; hovering over a window's maximize button displays pre-determined "Snap Layouts" fortiling multiple windows onto a display, and tiled arrangement of windows can be minimized and restored from the taskbar as a "snap group".[88][107] When a display is disconnected in amulti-monitor configuration, the windows that were previously on that display will be minimized rather than automatically moved to the main display. If the same display is reconnected, the windows are restored to their prior location.[108]
On October 21, 2021, Windows Subsystem for Android (WSA) became available to Beta channel builds of Windows 11 for users in the United States,[109] which allowed users to install and runAndroid apps on their devices. Users could install Android apps through any source using theAPK file format.[110] AnAmazon Appstore client for Microsoft Store was also available.[111][112][113][114] The Windows Subsystem for Android and Amazon Appstore became available to Release channel users in the United States on February 15, 2022, in Windows 11 Release build 22000.527.[115] On March 5, 2024, Microsoft announced deprecation of WSA with support ending on March 5, 2025.[116]
WSA was based on the Intel Bridge runtime compiler; Intel stated that the technology was not dependent on its CPUs, and would also be supported on x86-64 and ARM CPUs from other vendors.[114]
Setup
Home and Pro (sinceversion 22H2) edition installation requires internet connection and Microsoft account login (only if for personal use on Pro) is mandatory unless manually bypassed to create a local user.[117][118][119][120][121] However, Microsoft has since blocked one of the last remaining easy bypass methods that allowed local account creation during initial setup, complicating the bypass process further.[122][123] All other editions are excluded from this requirement.[105][124]
System security
As part of the minimum system requirements, Windows 11 only runs on devices with aTrusted Platform Module 2.0 security coprocessor,[125][126] albeit with some exceptions, see§ System requirements for details. According to Microsoft, the TPM 2.0 coprocessor is a "critical building block" for protection againstfirmware and hardware attacks. In addition, Microsoft now requires devices with Windows 11 to include virtualization-based security (VBS), hypervisor-protected code integrity (HVCI), andSecure Boot built-in and enabled by default.[127] The operating system also features hardware-enforced stack protection for supported Intel and AMD processors for protection againstzero-day exploits.[128]
In subsequent updates, Microsoft added several features based onartificial intelligence (AI), like live captions, background noise removal in videoconferencing, webcam auto-framing that follows the user's movements,[87] and AI-powered Bing Chat in the taskbar's search field.[129] Following the integration ofGPT-4 in Microsoft's other products, the company announced that by summer 2023, the newly releasedMicrosoft Copilot would add GPT-4 integration to the Windows taskbar.[130]
On May 20, 2024, Microsoft officially announcedRecall, a feature that uses a hardwareAI accelerator to locally store snapshots of the user's activity (including content transcribed using live captions), and which allows users to search through them. This feature is exclusive to devices certified under the "Copilot+ PC" branding.[131][132][133] Following pushback from the cyber security community, Microsoft delayed the feature in June 2024. A preview version will be added to the Microsoft Insider program at later date in order to test added security measures.[134]
Editions
Windows 11 is available in two main editions; theHome edition, which is intended for consumer users, and thePro edition, which contains additional networking and security features (such asBitLocker), as well as the ability to join adomain.[135] Windows 11 Home may be restricted by default to verified software obtained from Microsoft Store ("S Mode").[136] Windows 11 Home requires an Internet connection and aMicrosoft account in order to complete first-time setup.[137] This restriction is also applied to Windows 11 Pro sinceversion 22H2[121] as it was announced in February 2022, although a Microsoft account isn't required if it's not for personal use.[138]
Windows 11 SE was announced on November 9, 2021, as an edition exclusively for low-end devices sold in the education market; it is intended as a successor toWindows 10 S, and also competes primarily withChromeOS. It is designed to be managed viaMicrosoft Intune. Based on feedback from educators, Windows 11 SE has multiple UI differences and limitations, including Snap Layouts not containing layouts for more than two applications at once, all applications opening maximized by default, and Widgets being removed. It is bundled with applications such asMicrosoft Office forMicrosoft 365,Minecraft Education Edition, and Flipgrid, whileOneDrive is used to save files by default. Windows 11 SE does not include Microsoft Store; third-party software is provisioned or installed by administrators. To target organizations migrating from Google Chrome, Microsoft Edge is configured by default to enable the installation of extensions from theChrome Web Store.[139][140]
Other editions include Pro Education, Pro for Workstations, Education, Enterprise, Enterprise multi-session, IoT Enterprise, Enterprise LTSC, IoT Enterprise LTSC, Home Single Language, and Team; along with regional variations. These editions remain fundamentally the same as their Windows 10 edition counterparts.
Two new edition variants called IoT Enterprise Subscription and IoT Enterprise Subscription LTSC have been introduced inversion 24H2.[141]
Supported languages
Before the launch of Windows 11, OEMs (as well as mobile operators) and businesses were offered two options for device imaging: Component-Based Servicing lp.cab files (for the languages to be preloaded on the first boot) and Local Experience Pack .appx files (for the languages available for download on supported PCs). The 38 fully-localized Language Pack (LP) languages were available as both lp.cab and .appx packages, while the remaining 72 partially-localized Language Interface Pack (LIP) languages were only available as .appx packages.[142]
With Windows 11, that process has changed. Five new LP languages were added — Catalan, Basque, Galician, Indonesian, and Vietnamese — bringing the total number of LP languages to 43. Furthermore, these 43 languages can only be imaged using lp.cab packages. This is to ensure a fully supported language-imaging and cumulative update experience.
The remaining 67 LIP languages that are LXP-based will move to a self-service model, and can only be added by Windows users themselves via the Microsoft Store and Windows Settings apps, not during the Windows imaging process. Any user, not just admins, can now add both the display language and its features, which can help users in business environments, but these exact options for languages (both LP and LIP) still depend on the OEM and mobile operator.
Like Windows 10, Windows 11 follows Microsoft's Modern Lifecycle Policy. Each annual feature update has its own support lifecycle: two years for the Home and Pro editions, and three years for the Education and Enterprise editions. Microsoft has stated that Windows 11 provides no lifecycle guarantee if it has been installed on a machine that does not meet its minimum hardware requirements.[143]
Windows 11 receives annual major updates, though Microsoft sometimes adds major features in mid-cycle releases. Starting in 2022, in the Enterprise and Education editions, major features added in yearly releases will be turned off by default until the next yearly release, though these features can be manually enabled as agroup policy.[144]
Preview releases
TheWindows Insider program carries over from Windows 10, with pre-release builds divided into "Dev" (unstable builds used to test features for future feature updates), "Beta" (test builds for the next feature update; relatively stable in comparison to Dev channel), and "Release Preview" (pre-release builds for final testing of upcoming feature updates) channels.[145]
^Five updates were released: "Moment 1" with build 22621.675 on October 18, 2022 "Moment 2" with build 22621.1344 on February 28, 2023 "Moment 3" with build 22621.1778 on May 24, 2023 "Moment 4" with build 22621.2361 on September 26, 2023 "Moment 5" with build 22621.3235 on February 29, 2024

Known issues
Version 24H2, notably, has a longer than usual list of known issues. Some require updateddrivers or [free] software updates to fix, while others have yet to be fixed as of March 2025. E.g., broken biometrics and camera support on a limited number of devices, and some older games and applications not functioning properly or not working at all; e.g.,Asphalt 8 and Dirac audio improvement software (if cridspapo.dll is utilized).[146][147][148]
A supported processor and a solid-state drive At least 8 GB of RAM (minimum) At least 16 GB of RAM (recommended)
Official
The basicsystem requirements of Windows 11 differ significantly from Windows 10. Windows 11 only supports64-bit systems such as those using anx86-64 orARM64 processor;IA-32 andARM32 processors are no longer supported.[126] Thus, Windows 11 is the first consumer version of Windows not to support 32-bit processors (althoughWindows Server 2008 R2 is the first version ofWindows Server to not support them).[152][153] The minimum RAM and storage requirements were also increased; Windows 11 now requires at least 4 GB of RAM and 64 GB of storage.[154] Also for the first time,TPM 2.0 is now required, however,Original equipment manufacturers (OEM) can still ship computers without TPM 2.0 enabled upon Microsoft's approval.[125][155]S mode is only supported for the Home edition of Windows 11.[156]
In addition, for the first time, Microsoft enforces a processor model check before installation (although not on all editions, e.g., someIoT editions are excluded), where the processor model is checked against a Microsoftwhitelist. As of March 2025, the officially supported lists of processors includes eighth generation Intel Core CPUs (Coffee Lake) and later, AMDZen+ CPUs/APUs and later (which include the "AF" revisions of Ryzen 1000 CPUs, which are underclocked Zen+ CPUs that supplant Ryzen 1000 parts that could no longer be manufactured due to a change inprocess),[157] andQualcomm Snapdragon 850 and later.[158][159][160] The Intel compatibility list also includes the Intel Core i7-7820HQ, a seventh-generation processor used by theSurface Studio 2,[161] although only on devices that shipped withDCH-based drivers.[162]
The processor compatibility lists Microsoft provides are cumulative, e.g., all processors listed as compatible withversion 21H2 are also compatible withversion 24H2. However, newer version lists (post version 21H2) may omit older processor models, as these lists are primarily intended for use by OEMs, for newly manufactured devices. Regardless, as of February 2025, Microsoft now recommends thatconsumers simply ignore these lists and instead verify processor compatibility via the Microsoft PC Health Check app. This change was due to previous consumer confusion, initially perpetuated by erroneous reports from some news outlets.[163][164]
On May 20, 2024, Microsoft announced "Copilot+ PC"—a brand of Windows 11 devices that are designed to support enhanced artificial intelligence features. Copilot+ PCs require an on-boardAI accelerator, at least 256 GB of storage, and at least 16 GB of RAM. The first wave of Copilot+ PCs run the Qualcomm Snapdragon X Elite system-on-chip. x86-64-based Copilot+ PCs began to be announced later in the year, which are based on AMDRyzen AI andIntel Core Ultra CPUs.[131][132][165][133]
Unofficial
Devices with unsupported 64-bit processors are not blocked from installing or running Windows 11; however, a clean install or upgrade using ISO installation media must be performed as Windows Update will not offer an upgrade from Windows 10.[166] Additionally, users must also accept an on-screen disclaimer stating that they will not be entitled to receive updates, and that damage caused by using Windows 11 on an unsupported configuration are not covered by the manufacturer's warranty.[167][168]
In addition, various unofficial methods to bypass other Windows 11 official requirements, such as, but not limited to, TPM 2.0 exist; furthermore there also exists an official bypass method provided directly by Microsoft (whereas the installation itself remains unofficially supported).[169]
LegacyBIOS is no longer officially supported; aUEFI system and aTrusted Platform Module (TPM) 2.0 security coprocessor is now officially required.[105][149][173][174] The TPM requirement in particular has led to confusion as many motherboards do not have TPM support, or require a compatible TPM to be physically installed onto the motherboard. Many newer CPUs also include a TPM implemented at the CPU level (with AMD referring to this as "fTPM", and Intel referring to it as "Platform Trust Technology" [PTT]),[175] which might be disabled by default and require changing settings in the computer's UEFI firmware,[176] or a UEFI firmware update that changes the default settings to reflect these requirements.[177]
ARM64 version of Windows 11 requires theUEFI firmware withACPI protocol.
Starting with version 24H2,IoT Enterprise editions have officially reintroduced legacy BIOS support and eliminated the requirement for a TPM.[124]
Third-party software
Some third-party software may refuse to run on configurations of Windows 11 that do not comply with the hardware security requirement. After the release of Windows 11,Riot Games' kernel-levelanti-cheat system Vanguard—used inValorant and since May 2024 byLeague of Legends[178]—began to enforce the operating system security requirements, and will not allow the games to be run on the OS if secure boot and a TPM 2.0-compliant coprocessor are not enabled.[179]
WhileIoT Enterprise editions have always had slightly reduced official requirements compared to other Windows 11 editions, notably starting withversion 24H2, minimum requirements were further reduced and now differ significantly. These updated 24H2 requirements were announced on May 22, 2024, for both LTSC and non-LTSC editions.
For the first time since Windows 11 release, Microsoft has officially eliminated aTPM andUEFI minimum requirement for all systems running these editions and dropped the minimumDirectX version down to 10 (version 12 was previously required on23H2). Finally, the IoT Enterprise LTSC edition further drops the minimum required RAM to 2 GB and storage space to 16 GB.[124][141]
Reception
Pre-release
Reception of Windows 11 upon its reveal was positive, with critics praising the new design and productivity features.[180] However, Microsoft was criticized for creating confusion over the minimum system requirements for Windows 11.[181] The increased system requirements (compared to those of Windows 10) initially published by Microsoft meant that up to 60% of existing Windows 10 PCs were unable to upgrade to Windows 11,[182] which has faced concerns that this will contribute toelectronic waste.[183]
Microsoft has not specifically acknowledged this when discussing the cutoff, it was also acknowledged that thesixth andseventh generation ofIntel Core processors were prominently afflicted by CPU-level security vulnerabilities such asMeltdown andSpectre, and that newer CPUs manufactured since then had increased mitigations against the flaws.[101][184]
Speaking to IT news outletCRN, a dozen solution providers all felt that they "believe Windows 11 will be a meaningful step up in security, and they agree with Microsoft's strategy of putting security first."[184]
Research Vice President ofGartner Stephen Kleynhans felt that Microsoft was "looking at the entire stack from the hardware up through the applications and the user experience and trying to make the entire stack work better and more securely.[184]
Launch
Andrew Cunningham ofArs Technica gave a mixed but overall cautiously positive review of Windows 11 upon its release. He praised the improvements to its visual design (describing the new "Mica" appearance as reminiscent of the visual appearance ofiOS andmacOS, and arguing that Microsoft had "[made] a serious effort" at making the user-facing aspects of Windows 11 more consistent visually. He also praised window management, performance (assessed as being equivalent to if not better than Windows 10), other "beneficial tweaks". Criticism was raised towards Widgets' lack of support for third-party content, thus limiting it to Microsoft services only, regressions in taskbar functionality and customization. He also noted the inability to easily select default applications for common tasks such as web browsing, as it requires the user to select the browser application for eachfile type individually. Apart from the user interface, system requirements and Microsoft's unclear justification for its processor compatibility criteria remained a major sticking point for him. While some of the system requirements have brought greater public attention to hardware security features present on modern PCs, he argued that these could already be employed on Windows 10, albeit optionally. Cunningham concluded that "as I've dug into [Windows 11] and learned its ins and outs for this review, I've warmed to it more", but argued that the OS was facing similar "public perception" issues toWindows Vista andWindows 8. However, he noted that 11 did not have as many performance issues or bugs as Vista had upon its release, nor was as "disjointed" as 8, and recommended that users who were unsure about the upgrade should stay on Windows 10 in anticipation of future updates to 11.[101]
Tom Warren ofThe Verge described Windows 11 as being akin to a house in the middle of renovations, but that "actually using Windows 11 for the past few months hasn't felt as controversial as I had expected"—praising its updated user interface as being more modern and reminiscent ofiOS andChromeOS, the new start menu for feeling less cluttered than theWindows 10 iteration, updates to some of its stock applications, and Snap Assist. Warren noted that he rarely used the Widgets panel orMicrosoft Teams, citing that he preferred the weather display that later versions ofWindows 10 offered, and did not use Teams to communicate with his friends and family. He also acknowledged the expansion of theMicrosoft Store to include more "traditional" desktop applications. However, he felt that Windows 11 still felt like a work in progress, notingUI inconsistencies (such as dark mode and newcontext menu designs not being uniform across all dialogues and applications, and theUWP Settings app still falling back upon legacyControl Panel applets for certain settings), regressions to thetaskbar (including the inability to move it, drag files onto taskbar buttons to focus the corresponding application, and the clock only shown on the primary display inmulti-monitor configurations), and promised features (such as dynamic refresh rate support and a universal microphone mute button) not being present on the initial release. Overall, he concluded that "I wouldn't rush out to upgrade to Windows 11, but I also wouldn't avoid it. After all, Windows 11 still feels familiar and underneath all theUI changes, it's the sameWindows we've had for decades."[185]
Mark Hatchman ofPC World was more critical of Windows 11, arguing that it "sacrifices productivity for personality, but without cohesion", commenting upon changes such as the inability to use local "offline" accounts on Windows 11 Home, regressions to thetaskbar, a "functionally worse"start menu,Microsoft Teams integration having privacy implications and being a ploy to coerce users into switching to the service,File Explorer obscuring common functions under unclear icons, forcing users to scroll through many options to discourage changing the default web browser from Microsoft Edge, and that the OS "anecdotally feels less responsive, slower, and heavier than Windows 10". He concluded that Windows 11 "feels practical and productive, but less so than its predecessor in many aspects", while its best features were either "hidden deeper within", required specific hardware (DirectStorage, Auto HDR) or were not available on launch (Android app support).[186]
Market share
As of February 2025[update], Windows 11, accounting for 38% of Windows installations worldwide,[187] is the second most popular Windows version in use, with its predecessor Windows 10 still being the most used version in virtually all countries (withGuyana being an exception, where Windows 11 is the most used[188]), having over 2 times the market share globally. Windows 11 has an estimated 23% share of allPCs (the rest being other Windows editions and other operating systems such asmacOS andLinux), and an estimated 8.6% share of all devices (including mobile, tablet and console)[189] are running Windows 11.
